Vacuum V-Blenders & Dryers
The twin-shell V geometry splits and recombines the batch with every rotation — the fastest diffusive tumble action, now in a jacketed, vacuum-rated execution. Blend, dry and deaerate pharmaceutical and fine-chemical powders with essentially zero shear.
The Mixing Action
Split & Recombine
Each rotation divides the batch into the two shells and recombines it at the junction — a statistically efficient diffusive mechanism that reaches uniformity in fewer turns than a plain drum.
Vacuum & Thermal Shell
Jacketed shells and low absolute pressure dry the blend after it is uniform — or strip residual solvent from an already-dry API — in the same rotation cycle.
Intensifier Bar Option
A liquid-dispersing/de-lumping bar through the trunnion adds just enough energy for minor-ingredient dispersion or light agglomerate breakage without abandoning low-shear behaviour.
Where the PVB Series Earns Its Place
Strengths
- Fast diffusive blending with essentially zero attrition
- Blend and dry in the same vessel — no transfer, no re-segregation
- No product-zone shaft seal without the intensifier option
- Preferred pharma geometry — simple validation and total discharge
- Nitrogen loading and inert operation available
Typical Duties
- Final blending and lubrication of pharma granulates
- Post-blend drying and solvent stripping
- Deaeration of low-density powders
- Fragile and segregating blends
- Small-lot high-value specialty powders
Industries
- Pharmaceutical
- Nutraceutical
- Fine chemicals
- Cosmetic powders

V-blenders are commodity; vacuum V-blender/dryers are not. QuantumX engineers the fill fraction, rotation speed and jacket duty around your blend — and validates uniformity by thief-probe CV and drying by measured LOD curve before the machine is quoted.
Mix, Dry, React — One Vessel, Under Vacuum
At 10–100 mbar absolute, water boils between 7 °C and 46 °C — so heat-sensitive product dries at temperatures a conventional dryer cannot approach. Every QuantumX vacuum machine shares the same engineering: ASME jackets, vacuum-rated bodies, closed-loop solvent recovery, nitrogen back-fill for oxygen-free processing, and product-temperature control with full batch data logging.

One Vessel, Three Duties
Mix, react or granulate, then dry to spec — no transfer, no loss, no re-segregation.
Solvent Recovery
Condenser, receiver and cold trap sized to the duty; solvents come back as liquid.
Oxygen-Free
Evacuate and back-fill with N₂; ATEX and inert-loop control available.
Validated Cycles
Drying curve and endpoint measured in trial, warranted at FAT.
V-blenders are also built as standard atmospheric mixers — the same engineered geometry, jacket options and trial validation, without the vacuum train. Specify at enquiry.

V-Blender Dryers, Answered
What is a vacuum V-blender dryer?
A twin-shell V-blender built as a jacketed, vacuum-rated vessel. It blends by tumble diffusion and then dries or deaerates the batch under 10–100 mbar without transferring the product.
What fill level does a V-blender need?
50–60% of total volume is the efficient window; overfilling suppresses the split-recombine mechanism and stretches blend time.
When is the intensifier bar needed?
For dispersing liquids or breaking soft agglomerates during blending. Pure tumble operation remains available with the bar stationary.
